Abstract
The utility model discloses a single-tension-ring weight sensor, belonging to the field of tower crane monitoring. The device comprises a tension-ring weight limiter, and is also provided with a weight shaft and a pull frame plate, wherein the tension-ring weight limiter is connected with the pull frame plate by the weight shaft which is connected with an output cable; the weight shaft passes through a through hole at one end of the tension-ring weight limiter and is movably connected with the tension-ring weight limiter; and the outer side of the pull frame plate is fixed with an anti-rotation blocking plate, the edge of which is contacted with the weight shaft. The weight shaft is installed on the original tension-ring weight limiter, so that the single-tension-ring weight sensor not only realizes the control for maximum hoisting weight, but also can measure, record and display the hoisting weight in real time. Due to the combination of the tension-ring weight limiter and the weight shaft, the single-tension-ring weight sensor reduces the cost of a tower crane, simplifies the installation steps of the tower crane, and reduces the influence of environmental factor on the measuring result.
Description
Technical field
The utility model relates to a kind of weight sensor, specifically is a kind ofly can control the weight sensor that the biggest lifting capacity can show hoisting capacity again in real time with what single pulling force ring type weight limits device and weight shaft were used in combination.
Background technology
The tower machine is a most widely used conveying arrangement on the building ground, is bearing to grow on the building site and is transporting apart from the high-altitude.But because its lifting altitude height, to play liter weight big, danger coefficient is very big in use, will cause wire cable rupture in case play the ability to bear that liter weight surpasses steel rope, and weight falls to injuring by a crashing object people or the thing under the tower machine.Therefore be provided with the weight limits device on the existing tower machine, be used for controlling the biggest lifting capacity, prevent overwork, also be provided with weight sensor in addition separately, be used for measuring in real time, showing hoisting capacity.Two kinds of devices are installed on the tower machine simultaneously, complex installation process, complex structure, the cost height, environmental concerns is big.
Summary of the invention
For addressing the above problem, the utility model provides a kind of compact conformation, low, the simple single pulling force ring type weight sensor of installation of cost.
Single pulling force ring type weight sensor described in the utility model comprises pulling force ring type weight limits device, also is provided with weight shaft and the plate of trying to stop people from fighting each other, and pulling force ring type weight limits device is connected with the plate of trying to stop people from fighting each other by weight shaft, and weight shaft is connected with output cable.Through hole and pulling force ring type weight limits device that described weight shaft is passed pulling force ring type weight limits device one end flexibly connect.The pulling force ring type weight limits device tension masterpiece time spent, because of weight shaft and the flexible connection of pulling force ring type weight limits device, weight shaft is subjected to diametral load, leading sheave moves up and down, cause pulling force ring type weight limits device to rotate along weight shaft, though changed by force direction, diametral load big or small constant can not influence the measurement to weight.Weight shaft is converted to electric signal with force signal and is transferred to ECU (Electrical Control Unit) by output cable, is controlled at by ECU (Electrical Control Unit) to show gravimetric value on the read-out.
In the said apparatus, the described plate outside of trying to stop people from fighting each other is fixed with antiturning fastener board, and the antiturning fastener board edge contacts with weight shaft.Described antiturning fastener board is a rectangular metal plate, by screw retention on the plate of trying to stop people from fighting each other.Antiturning fastener board blocks weight shaft, prevents to rotate when weight shaft is stressed.
In the said apparatus, described plate and the pulling force ring type weight limits device two ends of trying to stop people from fighting each other are provided with mounting hole, are used for this device is fixed on the tower machine.
The utility model has been installed a weight shaft on original pulling force ring type weight limits device, not only realized the control to maximum lifting weight, and has realized real-time measurement, record, demonstration lifting weight.Both make up the cost that has reduced the tower machine, have simplified the installation steps of tower machine, have reduced the influence of environmental factor to result of a measurement.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Embodiment of the present utility model comprises pulling force ring type weight limits device 2, antiturning fastener board 4, be equipped with weight shaft 3 in the through hole of pulling force ring type weight limits device 2 one ends, weight shaft 3 two ends connect with the plate 5 of trying to stop people from fighting each other, be connected with output cable 7 on the weight shaft 3, on the plate 5 of trying to stop people from fighting each other, its edge contacts with weight shaft 3 antiturning fastener board 4 by screw retention.Try to stop people from fighting each other plate 5 and pulling force ring type weight limits device 2 outer ends are provided with mounting hole 1,6.
As shown in Figure 3, during installation, on crane arm 12 root top booms, weld an otic placode 11 in advance, this device plate 5 one ends of trying to stop people from fighting each other are fixed on the otic placode 11, track adjusting wheel 8 connects with this device other end by a plate 10, raising line 9 is walked around from track adjusting wheel 8, when slinging weight, raising line 9 is subjected to pulling force and track adjusting wheel 8 is applied pulling force, track adjusting wheel 8 applies pulling force by 9 pairs of pulling force ring types of connecting panel weight limits device 2, make weight shaft 3 be subjected to diametral load, weight shaft 3 is converted to electric signal by output cable 7 outputs with force signal.Pulling force ring type weight limits device 2 mouths and tower machine control loop be connected to prior art, do not repeat them here.
